And doing enough of this to restore safe temperatures within decades, not centuries, will require yet more electricity generation.

若想做足这类措施以至在未来几十年内，而不是几百年内，将温度调回安全范围，我们就需进一步提高发电量。

So our bodies work hard to stay warm from the inside out, and maintain a narrow, safe temperature range.

所以我们的身体从内到外都很努力地在保暖来使我们的体温维持在一个小且安全的区间里。

Does everyone in town have safe temperatures in their homes?

城里的每个人家里的温度都安全吗？

For one thing, you'd have to extract 20 gigawatts of energy to cool the volcano down to a safe temperature, which would take an estimated 16,000 years from start to finish.

原因之一是你不得不提取二十吉瓦的能量去将火山冷却到到一个安全的温度，这个过程从始至终将大概花费一万六千年。
